El infame bloqueo mmap utilizado en copy_from/to_user() puede ser problemático cuando se invoca dentro de otro mutex, ya que podría provocar interbloqueos. En el caso del código del temporizador ALSA, el patrón incorrecto se encuentra en guard(mutex)(&register_mutex) que cubre copy_from/to_user(), que se introdujo por error al convertir a guard() y que ya se había solucionado cuidadosamente en el pasado.
